The FAA posted new regulations under Part 107 on June 21, 2016. It mentioned “a person operating a small UAS must either hold a remote pilot airman certificate with a small UAS rating or be under the direct supervision of a person who does hold a remote pilot certificate. To qualify for a remote pilot certificate a person must demonstrate aeronautical knowledge.” The FAA doesn’t explain any content that will appear on the aeronautical knowledge test.

We’ve researched the FAA website and found a great place to start – Pilots Handbook of Aeronautical Knowledge. You can find the link here. You can download the PDF right here.
